The mare you just called annoying? She's desperate for her friends' approval and is frequently throwing them parties?
The earth pony you called ugly? She runs a farm with her immediate family and it's harvesting season, so she hasn't had a moment's rest in over a week.
The baby dragon you tripped? His closest friend treats him like a slave.
And that unicorn you just called an egghead? She just moved into town from a large urban city where she had no friends.
See the filly on the scooter? She can't even fly because her wings aren't strong enough yet.

Note that the first icon in the Flutterkill mosaic is exchangable, as `vest demonstrates here. This works especially well with Fluttershy icons. Some other mosaics are exploitable in this way, too.
